A Research Visit

An Interview with Ketterley
A scholar seeking answers
Matthew Rose Sorensen visits Valentine Ketterley to ask about Laurence Arne-Sayles and the alleged labyrinth. He is skeptical of the claims but wants to understand their intellectual appeal.
A guarded host
Ketterley resists some questions yet eventually proposes performing the ritual. The interview shifts from discussion into an experiment Matthew believes he can observe critically.
The Prepared Room

A Familiar Arrangement
Ritual objects
Ketterley lowers the blinds, lights a candle, and asks Matthew to stand facing the hall. He places Matthew’s messenger bag on his shoulder, saying the notebooks will be needed.
A clue in the floor
Matthew notices the candle fits a pale square in a repeated stain. He realizes Ketterley has performed the ritual many times and continues to believe in the passage.
The Name Addedomarus

A Chant with Conviction
A language of ceremony
Ketterley chants in a language Matthew cannot identify and repeatedly invokes Addedomarus. Matthew listens with amusement, planning to question him afterward.
Skepticism interrupted
The ritual’s effect arrives before Matthew can expose it. The surrounding sounds and air change, making the impossible experience immediate rather than theoretical.
The World Switches

Arrival in the Minotaur Hall
A sudden displacement
The outside world’s noise disappears, replaced by cold air and the sound of waves striking walls. Matthew opens his eyes in a vast room among minotaur statues.
Knowledge as captivity
Ketterley is at ease and delighted to have a healthy young man. Matthew’s understanding of the ritual changes instantly: it has brought him somewhere without his consent.
Piranesi Begins

A New Life in the House
The lost history
Matthew’s account of the ritual becomes inaccessible as time in the House erodes memory. Piranesi develops a life organized around tides, statues, and the Other’s visits.
A concealed crime
Ketterley can leave the House and retain what Piranesi forgets. The ritual’s consequences therefore continue long after the moment of arrival, transforming a brief deception into years of captivity.
